Fig. 16 is a plan View, on a reduced scale, of the cut and scored blankwhich forms the wrapper for the package of Fig. 13.

Referring irst to Figs. 1 to 8 there is illustrated a form of thepackage which is characterized by an outer wrapper, or container 10, ofpredetermined size and shape, and a predetermined quantity of aproduct,.such as, a two pound mass or unit ofsliced bacon 11 in whichthe slices have been allowed to remain in their original position in theslab. The bacon slices 11 are arranged in face to face, edge supported,and tilted relation, so that a predetermined quantity or weight thereofmay be positioned in the container, the slices being tilted more or lessas required by their depth which will Vary according to the thickness ofthe bacon slab.

The outer wrapper or container for the package is f formed from agenerally rectangular blank or sheet 12 of paperboard, which isrelatively liexible and which is adapted to be cut and scored orcreased, as shown in Figs. 5 to 8, so that it may be folded to provide acontainer of predetermined size and shape. The exact sheet material usedfor the blank 12 may be varied. Any sheet material which may be cut andscored as illustrated can be employed in the manufacture of the wrapper,the choice of the material being dictated by the nature of the specificproduct with which the wrapper is used.

The rectangular blank 12 is divided into container bottom and top orcover forming sections 13 and 14 by a transverse score line 15 whichconstitutes the hinge line connecting the two container formingsections. The bottom forming section 13 is provided with transversely extending score lines 16 and 17 which are parallel with and longitudinallyspaced from the transverse score line 15` and which are adapted to formthe bottom, front and back corner edges of the container. The transversescore lines' 16 and 17 extend 'between transversely spacedlongitudinally extending score lines 18, v19 and 20, 21, which arespaced inwardly of the opposite side edges of the blank 12. The scorelines 16, 17, 18 and 20 define the panel 22 which constitutes the bottomwall of the bottom or body section of the container. The score lines 17,19, 21 and the end edge 23 of the blank define the panel 24 whichconstitutes the front wall of the bottom section of the container. Theblank material is cut along the longitudinal lines 25 and 26 which arein alignment with the scoreI lines 18, l19 and 2t), 21, respectively.The cutting lines 25 and 26 extend between the ends of thetransversescore lines 15 and 16 and define therewith the panel 27 whichconstitutes the back wall of the bottom section of the container.

The marginal portions of the blank which extend along opposite sideedges thereof and outwardly of the longitudinal lines 25, 18, 19 and 26,2t), 21, respectively, are cut and scored to divide these portions intocontainer end wall and corner connecting panels. Since these blankportions are cut and scored in an identical manner, only the marginalportion at one side will be described in detail, corresponding lines andareas on the marginal portion at the other side being indicated by thesame numerals primed. The marginal portion at one side is dividedlongitudinally into panels 2S and 29 by diagonal outwardly divergingcutting lines 30 and 31, which cutting lines 30 and 31 terminate attheir inner ends at the intersection of the transverse score line 17with the longitudinal score lines and 21. The angles formed by thecutting lines 30 and 31 with the longitudinal score lines 20 and 21 areequal and determine the angle of inclination or slant of the front wallpanel 24 with respect to the bottom wall panel 22 when the container 10is in its final form. At its rearward end the panel 28 is scored on thediagonal line 32 which extends outwardly of the intersection oftransverse score line 16 with the longitudinal score line 20 and thelongitudinal cutting line 26. The score line 32 is parallel with thecutting line 30 which forms the front edge of the panel 28 and theselines together with the longitudinal score line 20 and the free outerside edge 33 of the panel 28 form a parallelogram which determines thecross sectional shape of the final package, the panel area 34 withinthese lines constituting the bottom end wall of the container. Thelblank is cut so that a panel section 35 of generally triangular shapeis provided between the score line 32 and the cutting line 26 whichforms arear corner connecting tab between the rear end of the end Wallforming panel section 34 and the end of the rear wall forming panel 27.A diagonal score line 36 is provided in the panel 28 within the end wallforming area 34 which extends forwardly and outwardly of the end of thetransverse score line 16 and which forms with the diagonal score line 32and the end portion of the outer edge of the panel a triangular tabsection 37 which is adapted to fold about the score lines 32 and 36 whenthe corner connecting tab section 3S has its outer face secured to theinner face of the rear side wall forming panel 27 and the end wall 34 ismoved from a collapsed position to an upright or set-up position. Afurther diagonal score line 38 is provided within the end wall formingpanel section 34 which extends rearwardly and outwardly from the end ofthe transverse score line 17 and which bisects the angle between thelongitudinal score line 20 and the forward end edge 30 of the panel, topermit the forward portion of the panel to fold upon itself when thefront corner connecting panel or tab 29 is secured to the inner facethereof in the area between the score line 38 and the end edge 30.

The front corner connecting tab or panel 29 extends outwardly of thelongitudinal score line 21 and is adapted to hinge about the latter whenit is connected to the end of the panel 34 and the latter is moved froma collapsed to an upright or erected position in setting up thecontainer. The panel 29 may be reduced in depth somewhat by cutting awaythe forward end edge of the blank at 39.

The top or cover forming section 14 of the blank 12 is provided with atransverse score line 40, which is longitudinally spaced from thetransverse score line 15, and transversely spaced longitudinallyextending score lines 41 and 42, the latter extending in alignment withthe longitudinal score lines 18 and 20, respectively, of the bottomforming section 13 of the blank. The score lines 40, 15, 41, and 42define a top forming panel 43. The 'blank is cut on the lines 44 and 45which are in longitudinal alignment with the score lines 41 and 42,respectively, andwhich extend to the end edge 46 of the blank. The scoreline 40 and the cutting lines 44 and 45 together with the end edge 46dene a top front wall forming panel 47 of approximately the same size asthe bottom front wall forming panel 24.

The opposite `side marginal portions of the cover forming section 14 ofthe blank 12 which extend outwardly of the scoring and cutting lines 41,44 and 42, 45, respectively, are 4cut and scored to provide identicalend wall forming and front corner connecting panels. Only one of thesemarginal portions will be described in detail, the corresponding linesand areas on the other being indicated by the same numerals primed. Themarginal portion of the blank which extends outwardly of thelongitudinal score line 42l and cutting line 45 forms a panel 48,

which is cut at its inner end on a diagonal line 49l extendingrearwardly and outwardly of the end of transverse score line 15 andgenerally parallel with the score line 32 and the cutting line 30 of thebottom end wall forming panel 34. At its other end the panel 48 isscored on the diagonal line 50 which extends outwardly and rearwardly ofthe end of the transverse score line 40 and which is parallel with theycutting line 49. The score lines 42, 50, and the cutting line 49together with the outer edge 51 of the panel 48 form a parallelogram anddefine a panel area 52 which constitutes the top end or tab sections`35, 35'.

wall 'of the container. The end of the panel 48 is cut to provide agenerally triangular end connecting tab portion or panel section 53which is freed from the end of the front end forming panel 47 along the`cutting line 45 and is 'adapted to be secured to the inner face of thepanel 47. A diagonal score line. 54 is provided in the panel 47 withinthe end wall forming area 52 which extends forwardly andv outwardly ofthe end of the transverse score line 40 and which is parallel with thescore line 36 in the bottom end wall forming panel 34. The score line 54defines with the diagonal score line 50 a triangular tab section 55which is adapted to fold about the score lines 50 and 54 when the cornerconnecting tab section 53 has its outer face secured to the inner faceof the front wall forming panel 47 and the end wall 52 is moved fromcollapsed to upright position.

The top cover forming section 14 ofthe blank 12 is provided with agenerally rectangular aperture 56 which extends from the top wallforming panel' 43 across the score line 40 into the front wall formingpanel 47 and which is provided with a transparent covering sheet 57 topermit the contentsof the finished package to be observed. A tabformation 58 may be' provided which projects into the aperture 56 forlabeling or. advertising purposes. The front wall panel 24 of the bottomsection 13 of the blank is cut away at 59 to correspond with theaperture in the front wall panel 47 of the cover section 14 when thesepanels are superimposed in the completed package.

In setting up the blank 12, -or'folding the panels of the same, to formthe collapsed container which is supplied in collapsed condition to theuser, the end wall forming and corner connecting panels 28, 28', 29, 29'and 48, 48' are rst folded to the positions shown in Fig. 6. The frontcorner connecting panels 29 'and 29 are folded inwardly about the scorelines 21 and 19, respectively. The bottom and top end Wallvformingpanels 28, 28 and 48, 48 are folded inwardly about the score lines 20,18 and 42, 41, respectively. The triangular portions of the bottom endwall forming panels between the score lines 38, 38 and the forward ends30, 30 of these panels are folded outwardly about the score lines 38 and38 and an adhesive is applied in the stippled areas indicated at 60, 60(Fig 6). The triangular sections 35, 35 and 37, 37' at the other ends ofthe end wall forming panels 28, 28 are folded outwardly about the `scorelines 36 ,36' and then inwardly upon themselves about the score lines32, 32' and an adhesive is applied on the uppermost or exposed face ofthe triangular sections 35, 35 as indicated by stippling in Fig. 6. Thetop end wall forming panels 48, 48 are first folded inwardly about thelongitudinal score lines 42 and 41, respectively, and thereafter thetriangular panel sections 53, 55 and 53', 55' at the ends thereof arefolded first outwardly about the score lines 54, 54 and then inwardlyupon themselves about the score lines 50, 50 and an adhesive is appliedto the exposed uppermost face of the end corner connecting sections 53,53k as indicated by stippling in Fig. 6. The front end wallformin`g'panels24 and 47- of the bottom and cover sections,respectively, of the blank are then folded inwardly about the transversescore lines 17 and 40, respectively, tofbring their end portions intooverlapping relation with the adhesive coated areas on the end portionsof the folded end wall panels. The blank is then in the partially foldedcondition shown in Fig. 7. Finally, the top wall forming' panel 43iandthe rear wall forming panel -27 are folded about the transverse scoreline 16 which brings the ends of the inner face of the rear wall formingpanel 27 into engagement with the adhesive coated areas of the cornerlconnecting panel The folding operations are then complete and the'container 10"is in collapsed condition asshownin Fig; 8V in which' it`issupplied to the user.

In order to set up theY container 10 for receiving the .sliced baconv11, Orother'm'erchandis'e, the entire cover section 14 and the rearWall`forming panel 27 of the bottom forming section 13 are hinged aboutthe bottom rear corner forming score line 16 to bring the rear Wall 27into upwardly and rearwardly inclined relation relative to the bottomwall 22 of the bottom forming section. This movement causes the end wallforming panels 34, 34' to` open outwardly about the bottom end cornerforming hinge lines 18 and 20 into upright position carrying with themthe bottom front wall 24 and bringing the latter into upright rearwardlyinclined position as shown in Fig. 4. The front ywall forming panel 47of the cover may then be hinged about the scoreline 40 to open up thecover and to cause the end walls 52, 52 to unfold or swing outwardlyabout the score lines 42, 41 into depending relation from the ends ofthe 'top wall 43. The sliced slab of bacon may then be inserted in thebottom forniing portion of the container and the slicesv tilted therequired amount to `cause the mass of bacon to conform to the depth andparallelogram shape of the container. One or more strips of transparenttape or any other suitable fastening means may be employed to secure thetop and bottom portions of they container in closed condition. Thecontainer is adapted to receive the same quantity, by weight, of baconslices, regardless of the variations in depth or thickness which areencountered in this particular product. yWnen the depth or thickness ofthe slab is above or below the average depth or thickness of this typeproduct, the slices are merely tilted a greater or lesser amount whichvaries the shape of the cross section of the mass formed by the stripsbut does not materially change the total area so that there may beconsiderable variation in the depth of the slab andthe packages will beuniform in size, shape and appearance.

The package may be formed as illustrated in Figs; 9 to l2, with asimplified form of blank which is cut and creased or scored as shownparticularly in Fig. 12. The blank 100 is generally rectangular in shapeand is divided into body and cover forming sections101 and 102 by atransversely extending score line 103 intermediate the end edges of theblank. v

The body or botto-m forming section 101 is divided by the transverselyextending score line 104, which is parallel to and longitudinally spacedfrom the score line 103 and the longitudinally extending transverselyspaced score lines 105, 106 and 107, 108 into bottom forming and rearside wall forming panels 109 and 110, the score lines 103,. 104, and 107dening the bottom wall forming panel 109 and the score lines 104, 106and 108 together with the end edge 111 of the blank defining the rearside wall forming panel 110.

The lbottom forming section 101 of the blank 100 is provided along itsopposite side margins with panellforming portions or extensions whichare cut and scored in an identical manner. Only one of these'sidemarginal portions will be described in detail, corresponding lines andareas on the other one being indicated by the same numerals primed. Themarginal portion 112 which extends outwardly along the longitudinalscore line 105, 106 is divided into inner and outer panel portions 113and 114- by longitudinally extending score line 115 and cutting line116, the latter extending inwardly from the marginal edge of the portion112 whichis in transverse alignment with the score line 103. The cuttingline 116 extends between a triangular tab portion 117 and a rectangularflap portion 118, which are divided off from the panels 113 and 114 bydiagonal and transverse score lines 119 and 120 on the respectivepanels, the score line 119 ex-v tending outwardly of the end of thetransverse score line 103 and the score line 120 extending from thepoint of intersection of the score line 119 with the longitudinalk scoreline 115, which is also the end of the cutting line 116. The panels 113and 114 terminate at the other end on the cutting lines 121 and 122,which are parallel with the score lines 119 and 120, respectively, thediagonal cutting line 121 extending outwardly of the end of thetransverse score line 104 where it intersects the longitudinal scorelines 105 and 106. The end marginal portion of the blank is also cut onthe oppositely directed diag onal line 123 to define with the diagonalcutting line 121 and the longitudinal score line 106 a triangular endtab 124 on the side wall forming panel 110 which is adapted to ybefolded about the score line 106. The score lines 105, 115, 119 and thecutting line 121 form a parallelogram which determines the crosssectional shape of the package, the area 125 enclosed within these linesconstituting the end wall of the bottom forming portion of the wrapperor container in the completed package.

The cover forming section 102 of the blank 100 is divided bylongitudinally spaced transverse score lines 126 and 127 into arectangular top forming panel 128 and adjoining rectangular front andrear wall forming panels 129 and 130. The top wall forming panel and thefront wall forming panels 128 and 129 are substantially the same size asthe bottom wall forming panel 109 and the rear wall forming panel 110while the rear wall forming panel or flap 130 is somewhat narrower thanthe rear wall forming panel 110. The flap 130 is provided with aT-shaped locking projection 131 integral therewith and extending fromthe end margin or edge 132 of the blank which is adapted to be receivedin a locking slit 133 provided in the rear wall forming panel 110. Thetop panel 128 and a portion ofthe rear side wall panel 129 are providedwith an aperture 134 which is covered with a suitable transparent film135 to permit the contents of the package to be observed.

ln forming the package with the blank 100, the unit or mass of slicedbacon, or other product 136, is positioned with the bottom edge or facein engagement with the inner face of the bottom wall forming panel 109of the blank and the bottom slices are tilted towards the score line 104while the rear wall forming panel 110 is folded upwardly about the scoreline 104 to its inclined position, the end corner tabs, 124, 124 lbeingfolded inwardly about the score lines 106 and 108, against the ends ofthe bacon mass. Thereafter the end wall panels 113, 113 are folded intoupright position about the score lines 105 and 107, and the triangularend tabs 117, 117 are folded inwardly about the score lines 119, 119'into engagement with the forward face of the rearwardly tilted baconmass. Thereafter the rectangular panels 114, 114' are folded inwardlyabout the score lines 115, 115 into engagement with the end margins ofthe top surface of the bacon mass and the end flaps 118, 118 are foldeddown into engagement with the exposed -faces ofthe triangular tabs 117,117. Thereafter the fro-nt wall forming panel 129 is folded about thescore line 103 upwardly and rearwardly over the face of the foremoststrip of bacon and the top cover panel 128 is folded about the scoreline 126 down into engagement with the top surface of the `bacon mass.The rear side iiap 130 is then folded about the score line 127 over theedge 111 of the rear wall panel 110 and the locking tab 131 is engagedin the slit 133 in the former. The end wall members 113, 113 may be heldin upright or assembled position with the contents of the package by theuse of transparent tape or other suitable yfastening means, oroverlapping portions of the end and/or cover walls may be provided witha pressure sensitive adhesive or the like which will hold them inpositionv as the wrapper is assembled with the merchandise so that thepackage will retain its shape.

Another form of the package is illustrated in Figs. 13 to 16 in whichthe blank 200 is cut and scored as shown particularly in Fig. 16. Theblank 200 is generally rectangular in shape and is divided into 'bodyand cover forming sections 201 and 202 by a transversely extending scoreline 203.

The body or bottom forming section 201 is divided by the longitudinallyspaced transversely extending score lines 204, 205 and the transverselyspaced, longitudinally extending score lines,206, 207 into bottomforming panel 208, rear side wall forming panel 209 and front side wallforming panel 210.

The bottom forming section 201 of the blank 200 is provided along itsopposite side margins with panel forming portions or extensions whichare cut and scored in an identical manner. Only one of these sidemarginal portions will be described in detail, corresponding lines andareasv on the other being indicated `by the same numerals primed. Themarginal portion 211 which extends outwardly along the longitudinalscore line 206 is divided into inner and outer panel portions 212 and213 by a longitudinal extending score line 214. The panel portion 212 isscored on parallel diagonal lines 215 and 216 which extend outwardly ofthe ends of the transverse score lines 204 and 205, respectively, to theends of the longitudinal score line 214. The diagonal score lines 215,216 and the longitudinal score lines 206, 214 form a parallelo gramwhich determines the cross sectional shape of the package, the areaenclosed within these lines constituting the end wall of the bottomforming section of the wrapper or container in the completed package.The panel 213 which extends outwardly of the longitudinal score line 214is rectangular in shape and its length corresponds to the dimension ofthe bottom forming panel 208 in the lengthwise direction of the blank.The blank is cut at one end of panel 212 to provide between the diagonalscore line 215 and the cutting line 217 which defines the side or endedge of the back wall forming panel 209 a generally triangular cornerpanel or tab portion 218 which is foldable about the diagonal score line215 and at the other end of panel 212 a generally triangular cornerpanel or tab portion 219 which is foldable about the diagonal score line216.

The top or cover forming section 202 of the blank 200 is divided bylongitudinally spaced transverse score lines 220 and 221 into arectangular top wall forming panel 222 of substantially the same size asthe bottom wall forming panel 208, a rectangular front wall formingpanel 223 of substantially the same size as front wall forming panel 210and a locking panel or ap 224. The iocking panel or flap 224 is providedwith an integral fastening means along the free end edge 225 of theblank which consists of two transversely spaced oppositely directed hookformations 226 which hook formations are adapted to be engaged inlocking relation in cooperating slit formations 227 in the bottom wallforming panel 208 when the package is completely closed.
